Sentence examples for constant current driver from inspiring English sources
The LED luminaire was powered by using either adjustable current supply (200 340 mA) or a constant current driver (350 mA) throughout the experiments.
The CNC controller also features a five-pin DIN connector with two of the pins conditioned to activate relays, one of these pins was utilised to control a constant current driver for a 405-nm wavelength, 1-mW laser sourced from Roithner LaserTechnik.
Each individual LED was controlled by a dedicated constant-current driver (WS2812B, WorldSemi, China) with 8-bit pulse-width-modulation (PWM) resolution permitting electronic luminance adjustment over a 2.41 log unit range.
The model is necessitated by the driver of our constant voltage driver (CVD -based eleCVD -basedelectrotactilering system, whapticeaturenderingd-loop, load-aware (i.e. fingertip systemioimpedance-awhich capability in contrast to constant-current-driver (CCD) systems.
The LEDs were driven at constant current by a switch-mode LED driver circuit (based on LT3518, linear technology) operating at a switching frequency of 2 MHz.
This driver is to provide constant current to LED regardless of its output voltage, but there is a minimum output voltage whereby the output current cannot be maintained as constant.
Prolonged operation of the driver through relevant reliability test revealed that this minimum voltage will increase due to degradation of the output transistor in the driver, and when this minimum voltage exceeds the operating voltage of the driver, it no longer provides a constant current to the LEDs.
Either a constant current or a constant potential is applied to the preweighed working electrode.
